TECNA WELD TESTER TE1700 

2.6 SETTING LIMITS 

 

LIMIT - A control mask is associated with each acquired weld spot, with 
three weld limits that may be selected among the following quantities: 

current

, 

energy

, 

time

, 

force

 and 

displacement

. You cannot select two 

identical quantities from the limits mask. If using the TE1710 Expander, 
you can configure up to 15 limits masks through the control unit's call 
signals.  

 

 

 

Enables access to the welding limit programming menu.
